DEEP-WELL PUMP.

Application led July 21,

The object of my invention is to provide a pump capable of raising largequantitiesof water for irrigation and for other purposes, from bored orArtesian wells of great depth, said pump 'being of simple construction,adapted for indefinite extension, and capable of economic operation. Inirrigation reclamation fields where, on account of eX- cessivepumping,the water level has been lowered, the favorite centrifugal pumps are nolonger available without the trouble and expense of making pits toreceive them Iin order to get them near the water. The pumps whichfollowed these centrifugal pumps, namely the single acting cylinderslocated at different levels in a cased Well are open 1.o the objection`ot insuil'icient ca' pacity to deliver the water the well was able to'supply. The double plunger. pump, Which has taken the place ot these,and in which one plunger operates above another in oppo` sitedirec-tion, while of greater capacity, is objectionable from aneconomical standpoint,

yin that| itrequires a costly arrangement of pump head, a double sct ofcranks, connecting rods, cross heads, and plunger rods, which lit onewithin the other. The operation of this type oi pump', especially in-sandy water, has always been costly and annoying, because no means'have been devised to prevent the water and sand from getting invbctween'the two plunger rods and causing them to 'eut and wear,resulting in the frequent wearing out and breaking of the pump rods, andthe consequent breaks in other portions of the pump. Moreover, thesepumps are not able to deliver the amount-of water many wells canfurnish` 'By my invention, I provide a pump which l may -appropriatelycit a multi-plunger ,cylinder Which-avoids all these obyeetions inv thatit is capable, by its simple and indefinite extension, of delivering'all the Water 'supplied,.an,d by its construction and Specieaton ofLetters Patent.

additional purposes of sustaining the cylinder, and containing andguiding the operating-rods.

2 is a downward extension of the discharge pipe 1, connected with it bya couplingl 3, which is formed with an internally projecting flange 4,upon which rests the head casting 3 of the upper section G of thecylinder, which isthus suspended within the extension 2. A screw ring` 7holds the head 5 down to its seat on the tlange 4, so that the interiorof the extension 2 is not in direct communication with the interior ofthe discharge pipe 1.

The suspending head 5 ol the cylinder section is formed below'ils topwith an annular series oi.' ports 8, which communicate exterior-ly withthe space 9 between the cylinder G and thc.extcnsion Q, and interiorlywith a port l0, opening through the base ol the head, which port 1() iscon- 13 is the upper section of a hollow plunger rod which passes downthrough the cylinder head, and has connected with its upper end thepropelling rod 14. The hollow plungerrod section 13, is connectedwithin' thel cylinder section G tol'a succeeding similar plunu i ger-rodsection`15,'by a coupling 1G which has ported extensions' 17communicating` exvteriorly with the interior of the cylinder andinteriorly with the hollow plunger-rod sections.

Upon the upper end of ,the coupling 1G is and having ports 19 madethrough it. These 'actuated valve Q0.

ports are controlled from below byfa spr-mg lpon the lower end of i l0the coupling 1G is ai'lother plunger 2l, also fitting the cylinder (i,and having ports 22 330,614 r y c #3 'this construction, any number ofcylinders may be connected end to end. The water can be taken in` at theend of each cylinder, each of which may be used as single or as double`acting pump. All the plungers can be o jerated by one plunger rod. I

The capacity of the pump is limited only bythe practical liowingvelocity of water through the discharge p1pe instead of being controlledby the area of its plunger.

The extension 2 of the discharge pipe, not only-serves to guide andsteady the cylinder at its bottonnbut .also serves as a suction pipe incase the water yrecedes below the top of the upper cylinder section 6.xIn case, however, that Said. cylinder Sectio-n is at all timessuiiiciently snbmergedeven while operating at its maximum capacity, theextension 2 is not necessary.
